结局指标
主要结局
Number of Subjects With Serious Adverse Events (SAEs)
时间窗: During the entire study period (from Day 0 up to Day 210)
Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.
Number of Subjects With Biochemical and Haematological Above Normal Levels
时间窗: At Day 0, 7, 30, 37 and 60
Among biochemical and haematological parameters assessed were alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\], creatinine \[CREA\], haemoglobin \[Hgb\]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were - normal, below and above.
Number of Subjects With Biochemical and Haematological Below Normal Levels
时间窗: At Day 0, 7, 30, 37 and 60
Among biochemical and haematological parameters assessed were alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\], creatinine \[CREA\], haemoglobin \[Hgb\]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were - normal, below and above.
Number of Subjects With Solicited Local Symptoms
时间窗: During the 7-day (Days 0-6) post-vaccination period following each dose and across doses
Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site. Relationship analysis was not performed.
Number of Subjects With Solicited General Symptoms
时间窗: During the 7-day (Days 0-6) post-vaccination period following each dose and across doses
Assessed solicited general symptoms were fatigue, temperature \[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)\], gastrointestinal symptoms (gastro) \[nausea, vomiting, diarrhoea and/or abdominal pain\], headache, malaise and myalgia. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever ≥ 39.5 °C. Related = symptom assessed by the investigator as related to the vaccination.
Number of Subjects With Unsolicited Adverse Events (AEs)
时间窗: During the 30-day (Days 0-29) post-vaccination period
An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset out-side the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.
Number of Subjects With Normal Biochemical and Haematological Levels
时间窗: At Day 0, 7, 30, 37 and 60
Among biochemical and haematological parameters assessed were alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\], creatinine \[CREA\], haemoglobin \[Hgb\]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were - normal, below and above.
Number of Subjects With Normal Haematological Levels
时间窗: At Day 0, 7, 30, 37 and 60
Among haematological parameters assessed were platelets \[PLA\], red blood cells \[RBC\] and white blood cells \[WBC\]. Levels of haematological parameters assessed in terms of normal laboratory values were - normal, below and above.
Number of Subjects With Haematological Levels Above Normal
时间窗: At Day 0, 7, 30, 37 and 60
Among haematological parameters assessed were platelets \[PLA\], red blood cells \[RBC\] and white blood cells \[WBC\]. Levels of haematological parameters assessed in terms of normal laboratory values were - normal, below and above.
